MACHINE FOR TWlSTING'M ETAL STRIPS OR'WlRE.

SPECIFICATION forming part of Letters Patent No. 540,513, dated June 4, 1895.

I Application filed December 24, 1894: Serial No. 532,796. (No model) To all whom it may concern:

Be it known that I, THOMAS M. POLYBLANK, of New York city, in the county and State of New York, have invented a new and Improved Machine for Twisting Metal Strips or Wire, of which the following is a full, clear, and exact description.

My invention relates to a machine for twisting metalstrips or wire, or likematerial, and it has for its object to provide a machine which will be exceedingly simple, durable and economic in its construction, and through the medium of which one or a number of bends may be made in a metal strip, a length of wire, or the equivalent, and whereby also simultaneously with bending the metal an aperture may be produced in the bent portion, since the prime object of this machine is tobend strips of metal in sections at angles to one another, whereby when a series of these strips are crossed a lattice will be produced, the strips being joined by passing bolts or their equivalents through registering apertures.

Another object of this invention is to so construct the machine that the twisting apiparatus may be adjusted as desired and any chine.

required number employed, and whereby the sections of the strips with apertures and the blank sections may be of any desired length and the apertures be made to center metal of various widths, and whereby further adjustable guides or shoes will be employed for maintaining the strip in position to be operated upon. 7

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the machine, illustrating a strip of metal held in the guides or shoes and ready to be operated upon or twisted. Fig. 2 is a view similar to Fig. 1, illustrating the metal strip as acted upon by the twisting devices. front elevation of one end portion of the ma- Fig. 4 is a section taken substantially Fig. 3 is an enlarged on the line 4 4 of Fig. 3.

Fig. 10 is a section taken substantially on the line 10 10 of Fig. 8. Fig. 11 is an inner face view of the section of the bed which is shown removed in Figs. 8 and 9. Fig. 12 is a side elevation of a slightly modified form of twisting device. Fig. 13 is a View similar to Fig. 12, the cover-plate having been removed. Fig. 14 is a section taken on the line 14 14 of Fig. 13, and Fig. 15 is a detail view of a portion of a strip that has passed through the machine.

In carrying out the invention a stationary bed A is mounted upon suitable legs, or is otherwise supported, and the said bed is provided with one or more, preferably two, lon gitudinal slots 10. At each end of the bed a vertical hanger, bracket or standard 11 is located, being firmly attached to the bed, and upon the top of each of said brackets or standards a box 12 is erected, and in these boxes a shaft 13 is journaled. The shaft is preferably provided near one end with a finger 14, adjustably located thereon, adapted for engagement with a stop 15 placed upon the bracket, the stop being angular, presenting a front and a rear face, and limits the rotation of the said shaft. The shaft 13 may be turned through the medium of a handle 13*, as shown in the drawings, or a pulley may be employed, or other means may be used instead of a handle. The shaft is preferably provided with a longitudinal groove 16,'as shown in Fig. 5, and from each bracket or standard 11 aitrack or rail 17 is forwardly projected, extending horizontally a predetermined distance over and beyond the fixed bed A, and these tracks or rails 17, as shown in Fig. 6, are preferably inclined upon their upper faces at opposite sides,

being somewhat V-shaped in cross section at this point.

The rails or tracks 17 support a sliding or movable bed B, the said bed being provided where it contacts with the rails, with substantially V-grooves in its under face, and with a stirrup 17, practically surrounding each track, as is likewise shown in Fig. 6 and likewise in Fig. 3. This stirrup is made in sections so that by removing, for example, the bottom section, the movable bed may be lifted up from the track.

One or a series of shoes 19 is adjust-ably mounted upon the movable or sliding bed B, and each shoe is provided with a slot 20 in its inner end, and the upper wall of the slot is cut away longitudinally, rendering the lower wall of much greater length, as shown in Fig. 5. These shoes or guide fingers 19 are attached to the bed preferably by passing bolts 21 through them and through longitudinal slots 22 made in the movable bed, as shown in Figs. 1, 2 and 5, the bolts being provided at their lower ends with suitable nuts and washers.

The shoes or guide fingers 19 are intended to receive and hold the strip of metal B while an adjacent section of the strip is being twisted at an angle to the original plane of the strip, as shown in Fig. 2, and this twisting is accomplished through the medium of one or more twisting devices 0 carried by the fixed bed A and operated from the shaft 13, and said devices will be described in detail later on.

In order that the metal strips shall remain properly in the months or slots 20 of the shoes 19 a finger 23, which maybe termed an anchor finger, is attached to the movable bed B in like manner as the shoes. This anchor finger extends rearwardly, or in direction of the fixed bed a predetermined distance, and terminates in a pin 24, the said pin being passed through an aperture in the end of the stripto be operated upon after that end has been bent at an angle to the body, as shown in Figs. 1 and 2, the said anchor finger being shown in detail in Fig. 4.

A shifting shaft 25 is journaled in the outer ends of the tracks or rails 17, and is provided at one extremity with a crank 26, employed as a handle, this crank being located at the end of the machine at which the handle 13 is placed, operating the shaft 13, and at the opposite end of the shifting shaft 25 a second crank 27 is secured, and both of the cranks 26 and 27 are connected with the movable bed through the medium of links 28. Thus by manipulating the crank 26, which is used as a handle, the bed B can be moved readily in a horizontal plane to and from the fixed bed, sliding on the tracks 17.

The twisting device ordinarily employed is constructed as shown in Figs. 7, 8, 9, 10 and 11. It comprises a body block 30, a twisting disk 31 carried by the said block, and actuating gears 32, connected with the block and driven from the shaft 13. The body block is provided with lugs 31, which are made to enter the slots 10 in the fixed bed A, and the said block is adj ustably yet firmly attached to the fixed bed A, preferably by passing bolts through a plate 33,having bearing against the under side of the bed and into the lugs 31, as illustrated in Fig. 5. The body block is provided in what may be termed its forward edge with a longitudinal slot 34, and at or near its center a circular opening 35 is made in the body block, extending through from side to side, and in this opening the twisting disk 31 is held to revolve. The slot 34 in the body block 30 connects with the opening 35 in which the disk is mounted to turn, and the disk is provided with a diametrical slot 37, which when the disk is in its normal position will register with and virtually constitute a continuation of the slot 34 in the body block, as shown in Figs. 7 and 8. The upper portion of the body block upon one side, is made in two sections, whereby one section is provided with a recess 38, which extends from front to rear and embraces about one-half of the opening 35, and in the vertical wall of the recess 38 a recess 39 is made, eccentric to the twisting disk 31, and the removable section 40 of the upper portion of the body block, which may be termed a cap plate section, is provided in its inner face with a groove 41, eccentric to the opening in its lower edge in which the disk fits, as shown in Fig. 11. The twisting disk is provided with a punch pin 42, held to slide therein, and the pin extends into the slot 37 and likewise beyond the periphery of the disk, being provided at its outer end with a head 43, and this head enters the recess 39 in the body block, and likewise travels in the groove 41 of the cap plate of said block. A channel 44 is made in the interior of the disk, being practically a continuation of the bore in which the punch pin is placed, the bore of the punch for the punch pin being however at one side of the opening 37 in the disk, and the channel 44 at the opposite side, and this channel 44 receives the punchings and conducts them to an outlet opening 45, extending through the disk from side to side. The gears 32 heretofore mentioned are 1ocated one at each side of the body block, being rigidly secured to the twisting disk through the medium of bolts passed through suitable apertures in both the disks and the gears. Each gear is provided with a slot 46, extending from the periphery inwardly past the center, and the said slots in the gears are of a length equal to the combined length of the slot 34 in the body block 30 and the slot 37in the twisting disk, as shown in Fig. 5; and the periphery of each of the said gears is provided with teeth 47, which extend from the solid portion about onefourth of the circumference of the gears, as is likewise shown in Fig. 5. The body block is provided with a box 48 upon itsupper edge, journaling the actuating shaft 13; and upon this shaft, at each side of the said box 48 a pinion 49 is adjustably yet securely fastened on the shaft 13, ordinarilyby means of a key entering the longitudinalgroove in theshaft, as shownin Fig. 5. These pinions mesh with the toothed portions of the gears 32, as shown in Fig. 3. As heretofore statedany number of these twisting devices may be placed upon the fixed bed A, and in operation-the metal strip, or.

varied.

The slots in all of the body blocks 30 will ,7 be in registry with the slots 37in the twisting disks when the finger 14 on the shaft 13 is in engagement with the forward side of the stop 15. The crank handle 26 is now manipu lated to force the movable bed, which with its attachments may be termed a carriage, in dif rectionof the fixed bed, whereupon preferably two'of the shoes will be carried between each two opposing twisting devices, as shown in Fig.2, and the strip will'have entered the slots 34 in the body blocks of these devices, and have passed into the slots 37in the twist ing disks. The punch pins4t3 of the twisting devices will at this time be held out from the slots 37 and free from the strip, as shown in Fig. 8, owing to the'head of the pin being in the extreme upper portion of the eccentric groove 41. The handle 13 is then reversed, whereupon the gearwheels 32 will be rotated, carrying with them the disks 31, and when the handle strikes the opposite side of its stop the position of the disks will be that shown in Fig. 9, and the punch by entering the lower portions of their grooves 41 will have been forced inward through the metal, producing an aperture therein; and as the strip is held horizontally in the several shoes the sections of the strip contained in' the twisting disks will have been twisted to stand at an angle to these sections in the shoes, as shown in Figs. 2 and 14;. By restoring the twisting disks to their'normal position and throwing the carriage forward the strip in its twisted shape may readily-be withdrawn from the machine.

' The blank sections of the strip being gaged by the two shoes passing between the body blocks, the sections with the apertures are gage'd by placing'on one'side of the body block a gage 7O slotted to register with the slot 34 in said block. These gages may be of different thicknesses and serve also to center the apextures in said sections. The gages are preferably supported by tie bolts passing through the body block and the twisting disk and have sliding movement upon their supports.

In Figs. 12, 13 and 14, I have illustrated a modified form of the twisting device, in which the body block 50 is made in two sections w and a, the latter section being the thinner,

as illustrated in Fig. 14. The body is provided with an opening 51 extending through it from side to side, which opening is of greatest diameter at the center, in order that the twisting disk 52 may be provided. with a circumferential rib or flange 53, as shown in Fig. 13, in which one section" has been removed, and one section, as in the device above described, is provided with an eccentric recess 54 and the other with an eccentric groove '55, to receive the head of the punch pin 56.

The twisting disk is provided with a slot 57 like that described in connection with the other form ofdisk, whichregisters with the slot 58 in the body block; but upon a portion of the flange or rib 53 a series of teeth 59 are produced,.representing about one-fourth of the circumference of the disk, and these teeth 59 are made to mesh with a pinion 60, located in a suitable opening 61 made in the body block, and the pinion is mounted upon the actuating shaft 13. Under this construction it will be observed that but asingle pinion is employed,.and-the gears 32 are dispensed with, making the action of the shaft more direct upon the twistingdisk.
